The object of the invention is to provide nacreous film is intimatelyand inseparably lustrous pearl cloth. united with the cloth.

It has been attempted to coat cloth with The union of the pellicle withthe cloth pearl essence in varnish or lacquer solutions, may beaccomplished by applying a liquid 5 by spraying or brushing the solutionon the or fluid adhesive to the cloth and then presssurface or bydipping the material to be coating or rolling the nacreous pelliclethereon, 50 ed in the solution, but it has not been possible or theadhesive might be applied to the pellito obtain agood result in thismanner owing to .cle, or the pellicle or the foundation might the factthat the solution sinks into the pores have in it an ingredient whichwill become 1 of the cloth and therefore does not form a suflicientlytacky when heat is applied to smooth reflecting surface which is mostescause the pellicle to adhere firmly.

The degree of transparencyand'the amount of luster may, be regulated bymaking the mixture richeror less rich in the pearl essence.

. Added ingredients may reduce the transparency or make the pelliclesomewhat more opaque. The translucency of the pellicle permits the lightrays to play between the crystalloids to bring out the lustrous effect.For

this purpose it is necessary to thoroughly incorporate the luster-givingparticles with the film-forming material in such manner and in suchproportion as to evenly distribute the particles with spaces between, inorder that light may play between them. The particles are extremelyminute spindleor rod-like bodies, transparent or translucent, andevidently prismatic, or having .refracting surfaces, and the lustrous,pearl-like effect which is obtained is due to the'refraction and reflec-4 The pellicle is best obtained by pouring or flowing the solutioncontaining the pearl essence onto the surface of a very smooth glass or,metal plate, or onto a smooth drumor cylinder, from which theexceedingly thin and flexible, yet comparatively tough pellicle isstripped. The side of the pellicle which was next the smooth surface onwhich it Was cast will be the brighter side, and this side willpreferably be placed outward when the pellicle is applied to the cloth.a

The thinness of the pellicle is an important factor, both for displayingthe nacreous appearance and for securing perfect adhesion to the clothfoundation. In the case of light fabrics it is especially desirable toavoid any material increase in the body or stiffness of the cloth. Thepellicle is preferably of such order of thinness that it possesseslittle or no sensible body, and I have been able to make andemploypellicles about one-half of one thousandth of an inch in thickness withexcellent results. Naturally the thickness may be varied for differentpurposes.

' While pellicles having a body of cellulose material are especiallyappropriate for my purpose, and are those particularly intended, I donot necessarily limit myself thereto, as

scribed, since it is contemplated that bright nacreous pellicles ofcellulosic material charged 'with the fish-scale luster might be aformed apart from the cloth to which they are subsequently applied, byother methods, as, for example, by extrusion.

I claim:
